SAFETY GAS-BURNER.

Specification of Letters Patent.

Patented July 28, 1914.

' Application filed April 13, 1914. Serial No. 831,469.

To all whom z't may concern Be it known that I, J OHN GAsrAn, a subject of the King of Hungary, resldlng at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Safety Gas-Burners, of which the following is a specification.

This invention relates to certain new and useful improvements in safety gas burners.

The ob ect of the invention is to provide a gas burner having a safety valve normally positioned open and automatically closed upon the dis-engagement of a closing ele ment adaptable for movement by any current of air sufficiently strong to extinguish the light of the burner.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings forming a part of this application and wherein like designating characters refer to corresponding parts throughout the several views :F igure 1 is a longitudinal vertical central sectional view through the burner showing the valve open and the light burning. Fig. 2 is a similar view with the light extinguished and the valve in its closed seating position. Fig. 3 is a top plan view of the device. Fig. 4: is a transverse sectional view taken upon line IVIV of Fig. 1, and, Fig. 5 is a perspective view of the operative mechanism removed from the outer casing.

Referring more in detail to the drawings, the funnel-shaped casing 10 is illustrated as screw-threaded upon the end of the gas supply pipe 11 and within which casing the automatic mechanism illustrated in Fig. 5 is adapted to be seated.

A. pan-shaped member 12 is provided with projecting lugs 13 on its outer face which are adapted to rest upon the top edge of the casing 10 and thereby support the mechanism positioned therein. A stirrup 14 depends from the bottom of said pan member and together with the intermediate oppositely-positioned brackets 15 support a disk 16 which is thereby positioned parallel with the under face of the pan member 12. A valve rod 16 is freely positioned through alining perforations 17 and 18 in the top 19 and bottom 20 respectively, of the pan. The said rod also extends through the central perforation 21 of the disk 16, which perforation is provided with a depending marginal flange 22adaptable as a valve seat for the valve 23 mounted upon said rod 16 and preferably formed of rubber. The valve 28 being flexible is mounted upon said rod by means of the loose collar 24: whereby a slight relatlvely swinging movement is possible between said rod and valve, as in the closing operation illustrated in Fig. 2.

The rod 16 projecting downwardly below the disk 16 is freely received within the slot 25 longitudinally positioned through the bottom cross member 26 of the stirrup 1 1 and thus allowing a lateral movement of said rod. Theupper end of said rod is provided with a pad 27 positioned beneath a ball or globular member 28 at the upper end of the rod and which ball is adapted to seat and be engaged by the point 29 of the yoke 30 mounted upon the pan top 19. When the ball is so engaged the valve 23 will be retained unseated.

The complete operation of the device is believed to be apparent from the present description in that with the ball seatedin contact beneath the point 29 of the yoke, the pad 27 will close the pan top perforation 17 while the valve 23 will be depressed in its open position, and thus allow the gas from the supply pipe 11 to travel as indicated by the arrows in Fig. 1 and escape directly beneath the pan flange 31 and be lighted to form the flame 82. In the event of a draft of air coming in contact with the flame, any quantity thereof sufiicient to extinguish the light would also force the ball 28 from its seated position beneath the point 29 and the same taking a movement to either of the two opposite sides as governed by the movement of the lower end of the valve rod 16 within the slot 25, will allow the pressure of the gas exerted upon the valve 23 to move the rod and said valve upwardly, thereby forcing the said valve upon its seat 22 and cutting off the supply of gas to the outlet of the burner. The pressure of the gas upon said valve 23 retains the same closed until forcibly unseated by again replacing the ball 28 beneath the yoke point 29, it being of course understood that the main valve of the supply pipe which is not herein illustrated is present in the pipe 11, the same as in the usual construction of burners.

lVhile I have herein shown and described the preferred embodiment of the invention, I do not wish to limit myself thereto, as various forms and modifications may be had which will fall within the spirit and scope of the invention.

WVhat I claim as new is 1. A burner comprising a funnel-shaped casing, a frame positioned therein and having a valve seat therethrough, a shiftable rod positioned through said valve seat, a valve secured to said rod, a yoke upon the top of said frame, a ball positioned upon the upper end of said rod and adapted for seating engagement beneath said yoke with said valve in its open position and adapted for disengagement from said yoke.

2. A device of the class described comprising in combination with a gas supply pipe, a funnel-shaped casing mounted upon said pipe, a pan mounted in the open end of said casing and. spaced from the inner side thereof providing a gas exit passage, a depending frame upon said pan having a slot in the bottom portion thereof, a disk carried by said frame, a depending flanged valve seat centrally carried by said disk, a valve rod projecting through said slot and valve seat and extending above the top of said pan, a valve positioned upon said rod beneath said valve seat, and means adapted for releasing said rod for closing said valve upon a lateral tilting of said rod.

3. A device of the class described comprising in combination with a gas supply pipe, a funnel-shaped casing mounted upon said pipe, a pan mounted in the open end carried by said frame, a depending flanged valve seat centrally carried by said disk, a valve rod projecting through said slot and valve seat and extending above the top of said pan, a valve positioned upon said rod beneath said valve seat, a yoke upon the top of said pan having a pointed central portion, a ball upon the upper end of said rod contacting beneath said point with said valve in its unseated position and adapted upon a sidewise movement for disengagement from said point upon a seating of said valve.

4. A device of the class described comprising a gas supply pipe, a funnel-shaped casing upon the end of said pipe, a frame mounted within said casing and having perforations therethrough in alinement with said pipe, a valve seat surrounding one of said perforations, a valve rod extending through said perforations, a valve freely pivoted upon said rod and adapted for engagement with said seat, a yoke upon the top of said frame having a central point, a ball upon the top of said rod adapted for normally contacting beneath said point with said valve in its open position, the said valve being adapted for automatic closing upon a side shifting of said rod with said ball disengaged from said point.

In testimony whereof I afiix my signature in presence of two witnesses.
